Since the upper scoop is going well I thought by myself "lets go with the lower scoop". Damn that wasn't a good idea. I drilled the wholes but when I test fitted the lower scoops I'm not really sure that it's fitting very well.

Now I'm not really sure that the lower scoops are the once from mustangs to fear. These are ordered seperatly with mustangs unlimited.

When I look to the on the front (where the door is passing). I see that there is a small lip that will cause me problems in making a straight line from the door. Would it not be better to cut that whole part away?

When I look on the end I see it's not fitting at all. There is a big gap and I'm not really sure here what to do with it. Would some screws help me with that?

Who can suggest me on that?
